gramming" should not be used for the initial start-up, as the factory settings are always
used until the 1st communication (setting via objects is ignored).
Select, whether motion is to be detected
constantly or brightness dependent
.
Settings for brightness dependent motion detection:
The
brightness dependent motion detection
can be used via separate threshold
values for switch-on and switch-off or dependent on daylight. The separate threshold
values are ideal for controlling the light in rooms which are only illuminated by artifi-
cial light. The daylight dependent control is ideal for rooms with daylight and artificial
light.
For
daylight dependent motion detection with separate switch-on and
switch-off threshold values
activate, as required, the objects for setting the thres-
hold values. Then specify the switch-on and switch-off values (brightness range). The
switch-on value is the value, below which the room should be lit in the event of move-
ment. The switch-off value should be higher than the brightness value of the artificially
lit room.
If the indoor light level is above the switch on limit value, but below the switch off limit
value and the motion is still ongoing, or if another motion is detected before the end
of the switch-off delay, then the switch-off delay time period starts over. Only when the
light level exceeds the switch-off limit value is the switch-off delay no longer extended.
If the master output has detected the value for the end of the motion, then the light le-
vel must be below the switch-on limit value before any other motions are detected.
For the
daylight dependent motion detection
activate, as required, the objects for
setting the threshold values/hysteresis and waiting period. Then specify the switch-on
value. This is the value, below which the room should be lit in the event of movement.
